A shaft sealing arrangement includes at least two seal rings radially enclosing a rotating shaft so as to define a clearance between the shaft and the at least two seal rings. A sealing oil supply channel is disposed between the at least two seal rings and a pump is configured for pumping a sealing oil through the sealing oil supply channel in a radial direction towards the shaft so that the sealing oil subsequently flows through the clearance in a first axial direction toward a first side of the sealing arrangement and in a second opposite axial direction toward a second side of the sealing arrangement. The sealing oil is collected on the first and second sides and at least partially reintroduced into the sealing oil supply channel. At least one seal ring includes a sealing oil return channel and at least a portion of the sealing oil flowing through the clearance exits the clearance in a radial direction through the sealing oil return channel and is at least partially collected and reintroduced into the sealing oil supply channel.
